The prolific Dutchman is not thinking about leaving his current club right now, but he did not exclude the possibility of furthering his career at the Estadio da Luz
The Netherlands international, who did not play a single minute at Euro 2012, has recently been tipped to join Benfica should Oscar Cardozo depart the Estadio da Luz.
De Jong insisted that he has not been approached by the Portuguese club, but did not rule the possibility of a new challenge in his career.
"I have only read about Benfica's interest on the internet," he told Antena 1. "If Benfica want me, they will have to talk to Twente.
"They are a great club, I played against Benfica a few months ago. They play good football and have good players.
"I am happy at Twente, but it would be a good club to take the next step in my career. I am sure that I could learn a lot there and improve as a player.
"Let's wait to see if there is something concrete."
Should the move go ahead, the 21-year-old would be reunited with former Tukkers attacker Ola John, who signed for the Portuguese giants in May in a reported €9 million deal.
De Jong joined the Dutch side in 2009, and scored 31 competitive goals this season.
